SPECIFICATION forming part of Letters Patent No. 298,492, dated May 13, @884.

Application filed June 23, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JOHN L. NEWMAN, a citizen of the United States, residing at West Point, in the county of Troup and State of Georgia, have invented certain new and useful Improvements in Rotary Blowers; and Ido de-' clare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to blowers for ventilating or separating machines, or the like; and the novelty consists in the construction and arrangement of parts, and in the adaptationj of the same for efficient service, as will be more fully hereinafter set forth, and specifically pointed out in the claim.

The invention is fully illustrated in the accompanying drawings, which form a part of this specification, and in which- Figure l is a side elevation; Fig. 2, an end elevation of the discharge end; Fig.3, a detail in elevation, showing the adjusting-slide; Fig. 4, a detail showing the means for hanging the main shaft. Fig. 5 is a. detail View of the casing with the metal drum in position, one side of the casing being removed; and Fig. 6 is a detail view of the inner surface of one of the sides of the casing, showing the form of the groove in which the sheet-metal plate is received.

Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A designates the main frame, in which is journaled, at a, the powertshaft B, having suitable power-connections, as b, and being connected to the blower-shaft G by means of a belt, 0, which operates over the pulley B on the shaft B and the pulley 0 on the shaft 0. This blower-shaft O is hung on pivots D, 5 which pass through frames D, secured on the sides of the blower-case, which sides have central apertures, through which the said blowershaft operates. The frames D are secured on the sides of the case by bolts (1, and the shaft,

0 may be readily disengaged or the necessary 0 take-up to compensate for wear may be accomplished by the proper manipulation of the Screws D.

F designates the adjusting-slides, each having a turned-up edge, f, of sheet metal, and a 5 semicircular opening, f, which, when the slides are closed, receive the shaft 0. These slides are slotted at f, to receive pins f on the side of the casing, and they are adapted to be adjusted at will, to modify the feed of air as the requirements of the machine may sugest. b H designates the sides of the casing, having the ordinary form of a drum and a chute, and

each of these sides is provided on its inner face with a groove, h, formed sufficiently far from the edges to allow securing-bolts I to be operated between said grooves and edges. The grooves have, when properly formed, two parallel plane portions, J and J, and a circular o portion, J

K designates the spout, having a contracted exit, k, the body of which is adapted to be clamped between the sides H.

In putting the parts of the casing together it is only n cessary to place one side and the spout K in position, take a sheet of metal, as L, and insert it in the groove h, so that its ends will over and under lap the spout, put the re maining side in position, and attach the bolts I, when the blower-case is complete. Iattach importance to this construction of the blowercase, to the means for hanging the blowershaft, and to the adjusting-slides F.

Having thus described theinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-- In combination with the case and shaft 0, the adjusting-slides F, having semicircular openings f, slots f and upturned edges f, and the guide-pins f, as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
